An equilateral triangle is circumscribed about a circle of radius - 'r' and a square is inscribed in the circle. If the area of the triangle is T and the area of the square is S, then find T/S.
I don't know what you mean by An equilateral triangle is circumscribed about a circle of radius - 'r' but I will try to interpret it.
Just set a variable, calculate the area of each figure, and get (3 sqrt 3) /2.
